WoW Macro - Reloading UI Notifier

Reloads your UI, notifying your group, setting AFK (which clears when you move when you're back anyway)

/afk reloading UI
/run SendChatMessage("reloading my UI - afk for a sec", ((UnitInRaid("player")and "RAID")or(GetNumPartyMembers()>0 and "PARTY")or "AFK"));
/console reloadui

Use: Reload your UI, send a message to your party/raid telling them you're doing so and set an appropriate /afk message.
